The repair you requested this time was significantly larger than usual.
It took about two months for the product to be delivered.
This pre-mast tank was purchased about 8 years ago.
It is now a rare model, but its mechanism is the same as the later Mast Tank hand-wound model.
There are some minor differences in specifications,
Normally it doesn't take that long to repair.
This time the spring had broken and was replaced during the overhaul.
But it doesn't work...
I tried to find the cause and adjusted it again but it still didn't work.
This was the first overhaul since I purchased it.
There is wear on various parts other than the mainspring and there are also problems with the spring parts.
By replacing each part, it was finally completed.
Normally, the cost of each part is charged separately from the repair cost,
Since this was a watch purchased at our store, we were able to use stock parts.
The overhaul fee is ¥16,500 and the mainspring fee is ¥8,800 only.
Now you can use it forever!
